Umgangatho ophezulu woShishino we-ASME B16.34 weglowubhu wevalve umzi-mveliso waseTshayina
Yintoni i-ASME B16.34 ivalve yeglowubhu?
Ivalve yeglowubhu ye-ASME B16.34lolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the ngaphakathi ubukhulu, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wokuhlala weIvalve yeglowubhu ye-ASME B16.34inokulawulwa kakuhle ngesiqu esikrufu.
iIvalve yeglowubhu ye-ASME B16.34ingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi zevalvu ehleli enye zisebenzisa ikheji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokhelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu zokuqukuqela kwevalve ethile.Isenokuguqulwa ngokulula ngotshintsho lweziqendu zetrim ukutshintsha uphawu lokuhamba okanye ukunika umthamo oncitshisiweyoukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukupheliswa kwe-cavitation.
Iipateni zoMzimba we-ASME Globe, kukho iipateni ezintathu eziphambili zomzimba okanye uyilo lweevalvu zeGlobe, ezizezi:
- 1).Ipateni eMiselweyo (ekwabizwa ngokuba yiPateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-engile
UmGaqo wokuSebenza oIvalve yeglowubhu ye-ASME B16.34
Ivalve yeglowubhu yenziwe ngediski eshukumayo kunye nesitulo seringi esimileyo kumzimba ongqukuva.Isihlalo sevalve yeglowubhu siphakathi kwaye sihambelana nombhobho, kwaye ukuvulwa kwesitulo kuvaliwe ngediski.xa i-handwheel ijikelezwa ngesandla okanye nge-actuator, i-disc movement ilawulwa (iyancipha okanye iphakanyiswe) ngokusebenzisa i-valve stem.Xa idiskhi yeglowubhu yeglowubhu ihleli phezu kweringi yesitulo, ukuhamba kuyekiswa ngokupheleleyo.
Eyona nto iphambili ye-ASME B16.34 ivalve yeglowubhu
- 1).Izakhono zokutywina ezilungileyo
- 2) Umgama omfutshane wokuhamba wediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglowubhu ze-ASMEzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo;
- 3).Ivalve yeglowubhu ye-ASME ingasetyenziswa njengevalve yokumisa ngokuguqula uyilo kancinane.
- 4).Tnalu uluhlu olubanzi lwezakhono njengoko lufumaneka kwitee, iWye, kunye nezimbo zomzimba ze-engile.
- 5).Easy Machining kunye nokuphinda kuvele izihlalo, ngeenjongo ezahlukeneyo.

Iimveliso zibonisa: ASME B16.34 ivalve yeglowubhu
Ukusetyenziswa kwevalve yeglowubhu ye-ASME B16.34
ASME Globe iValveisetyenziswa ngokubanzi kuluhlu olubanzi lweenkonzo;zombini uxinzelelo oluphantsi kunye neenkonzo zoxinzelelo oluphezulu lwamanzi.Usetyenziso oluqhelekileyo lweevalvu zeglowubhu zezi:
- 1).Yenzelwe umbhobho ophuma rhoqo, okanye ukucinezela ulwelo kunye nesiphakathi segesi
- 2) Ulwelo: Amanzi, umphunga, umoya, i-petroleum ekrwada kunye neemveliso zepetroleum, irhasi yendalo, i-gas condensate, izisombululo zetekhnoloji, ioksijini, ulwelo kunye neegesi ezingezizo.
- 3).Iinkqubo zokupholisa zamanzi ezifuna ukulawulwa kokuhamba.
- 4).Inkqubo ye-oyile ye-fuel efuna ukuvuza kokuqina.
- 5).Iinkqubo zokudlula ivalve yokulawula.
- 6).Iindawo zokungenisa umoya eziphakamileyo kunye neendawo ezisezantsi zokukhupha amanzi.
- 7).I-oyile negesi, amanzi okutya, ukutya kweekhemikhali, ukucokiswa, ukutsalwa komoya okucondenser, kunye neenkqubo zokukhupha amanzi.
